reissue specification; matter printed in italics indicates the additionsmade This invention consists in a louvre shutter blind or the like whichis mounted in an adjustable manner so that the angle of the louvre maybe varied for the purpose of promoting ventilation and in some cases forproviding blackout condition, if desired.

The present invention aims to provide a form of construction in whichlouvres or lathlike shutters are mounted in metal holders or end memberspivoted in a longitudinal manner and capable of being rocked or turnedupon their respective pivots by a system of levers and a singleoperating bar common to all of the louvres.

The present invention also relates to means carried by the metal holdersor end members for the louvres, whereby access of wind and/or rain isprevented when the louvre or shutter is in the closed position.

Adjustable louvres are known, but the present form of constructiondiffers therefrom in that it is of easy manufacture at a relativelysmall cost, is capable of mass production and is quickly assembled.

According to the present invention there are provided two stiles ormetal fittings which are of channel or boxlike formation and consist ofa face portion and two flange portions one of which is recessed, saidchannel fittings being of slightly greaterlength than the sum of thewidths of the louvres when closed.

Each louvre which may be of glass or other material is mounted at eachend in a slotted or channeled end member or metal holder adapted to besecured as by a riveting action to a pivoting member, the said memberbeing formed with a bearing portion received in a hole in the respectivemeta] fittings and having a flanged portion which engages the inner faceof the said fitting. The pivoting members are freely mounted in one ofthe said fittings so as to turn easily in the holes therein.

Each of the pivoting members mounted in the other fitting have an armextending therefrom, the said arm being either integral with thepivoting member or secured thereto.

The outer or free ends of the respective engage relspective slots formedin a common operating member which is housed within. said fittings andis movable therein in a truly longitudinal manner by a suitable handleor lever or other means capable of imparting said longitudinal movementin either direction of. the said operating member.

The channeled end members or metal holders 30, 1949, Serial No.'102,381.er 22, 1942 (Eli. 20-432) Matter enclosed in heavy brackets I: appearsin the original patent but forms no part of this for the louvres are ofa length substantially equal by reissue to the width of the louvre. Theportion of each flange of the channel members on opposite sides thereofand at the ends thereof is cut away so that in the closed position ofthe louvres the latter lie closely face to face where they overlap oneanother, thus ensuring a watertight and weathertight closing of theshutter. The metal holders have a turned over portion to retain thelouvre in the channels.

It has been found that wind and rain will pass between the metal fittingwhich is secured to the usual mullions, and the respective metal holdersfor the louvres and therefore it has been found necessary to providebridging means for preventing this taking place.

In order to prevent ingress of wind and/or rain a bridging member isprovided to bridge the space between the metal fitting and the channeledend members and is carried by the latter. The end members for thelouvres each have a protecting strip disposed at right angles theretoand being formed either integral therewith or secured thereto in anapproved manner. The bridging member is of channel section and adaptedto receive the said protecting strip within it when the shutter isclosed. In order that the bridging member may move in synchronism withthe louvres the said member is pivotally connected to the lower end of.each of the protecting strips of the metal louvre holders.

To provide the protecting strip for each louvre end member the said endmember may be formed from a single sheet of metal bent or pressed toform a channel section with the protecting strip formed as a web atright angles to one side of the channel.

For instance commencing with the protecting strip portion there is aflange portion at right angles thereto formed of a double thickness offolded metal then a base at right angles thereto, and finally anotherflange portion at right angles to the said base and parallel with thefirst double web portion. Viewed in section the louvre holder comprisesfor example, a vertical protecting strip, a vertical base for thechannel and two horizontal flange portions for the channel between whichthe louvre is fitted, the said horizontal flange portion adjacent to thesaid protecting strip being doubled upon itself to form two thicknessesof the metal. If it is not desired to form the above double foldedportion, the protecting strip may be formed from right angle sectionmaterial welded or otherwise secured to the louvre holder.

In assembling the invention the respective pivoting members are placedin their respective holes in the metal fittings and each has arectangular projection which is passed through a slot in the respectiveend members and is riveted over or welded to retain it in operativerelation with respect to the stile. The glass or other louvres are thenplaced in the respective channeled end members.

In order that the invention may be more readily understood, referencewill now be made to the accompanying drawings wherein:

Figure 1 is a perspective View illustrating one end of a louvre blind orshutter made in accordance with the present invention and illustratingthe attachment of a bridging member to the end channel members.

Figure 2 is an elevational view looking towards the inside of one of themetal fittings and showing the operating arms of the pivoting means forthe respective louvres and the longitudinally movable member which movesin conjunction therewith.

Figure 3 is a detail view in closed position illustrating in sectionalplan the bridging member, its pivotal attachment to a channel endmember, the pivoting means for the latter and the functional relation ofthe bridging member to the recessed flange of the metal fitting.

A pair of metal fittings In of channel formation and consisting of aface portion and two flange portions one of which is recessed, isprovided for each set of louvre shutters, each of said fittings beingsecured to the usual mullions H and together form a housing within whichpivoting and operating means for the louvres are received. At suitabledistances apart holes are drilled in the metal fittings Ill to receivethe bearing portion 12 of the pivoting members for the channelled endmembers l3 which support the louvres M.

The pivoting members have a flanged portion l5, see Figure 3, whichengages the inner face of the respective metal fittings In, the saidpivoting members also being secured to the channelled end members I3 bymeans of a turned over or riveted portion l6 which has been passedthrough a slot or hole formed in the end member for this purpose.

Each of the pivoting members disposed in one of the said metal fittingsIll has an arm ll' extending therefrom the outer end of which has apivot 18 adapted to engage a transverse slot l9 formed in alongitudinally movable operating member 29, see Figures 2 and 3. Thesaid operating member 20 has an operating arm 2| or other suitable meansfor moving the said member 20 in a truly longitudinal manner within thesaid fitting.

The channelled end members l3 as illustrated are formed from one pieceof metal pressed to the desired shape, for forming a protecting strip atright angles thereto.

The said end members 13 illustrated are channelled to receive the louvrel4 and are formed with lips 23. Portion of each flange 24 of thechannelled end members l3 on opposite sides thereof is cut away at 25 sothat in the closed position of the louvres M the latter lie closely faceto face where they overlap one another thus ensuring a watertight andweathertight closing of the shutter when in the closed position seen inFigure 3.

A ng member 26 of channel shape and having two flanges is provided tobridge the space between the metal fittings l and the channelled endmembers 13 in their closed position. This bridging member 26 is securedby a pin 21 and slot 28 form of connection to the protecting strip ofthe said end member I3, the said strip being either integral with theend member l3 or attached thereto.

As illustrated the channelled end members [3 are formed from a singlesheet of metal bent or pressed to form a channel section with the twoflanges 2 3, and a protecting strip 26 attached thereto.

When in the closed position the bridging member 26 bridges theprotecting strip 29 by means of its two flanges, one of which ispivotally connected to the respective protecting strips while the otherflange enters the recess provided in the respective web of the metalfitting I!) provided to receive it.
